BOBBlN-CATCH FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 373,261, dated November15, 1887.

Application filed July 8, 1887.

To all whom it may concern.-

Beitknown that I, ISAAC L. ALLEN,of Brooklyn, in the county of Kings andState of New York, have invented a new and useful Improvement in BobbinCatches for Spinning- Machinesof which thefollowing-isa full, clear, andexact description.

In machines for spinning yarn or rope the bobbins on which the yarn iswound are ordinarily arranged axially within the fliers of themachine,and have both an independent rotary motion and longitudinaltravel on and along the spindle'of the fliers. These two independentmotions are communicated to the bobbins by means of a revolving head orbutton-carrier attached to a longitudinally-sliding andaxially-revolving sleeve, and fitted with a button which engages with acatch upon one head of the bobbin.

Heretofore the bobbin-catches in use have usually consisted of a simpleplate nailed upon the outer face of the one head of the bobbin over arecess or cut-out portion in said head, at a suitable distance from theaxial center of the bobbin, said plate having a square or oblong openingin it, which faces the recess in the bobbin-head, but is narrower thanit, whereby the plate forms opposite straight overlapping flanges forengagement with the head of the button which drives the bobbin. Saidbutton has two separate functions-that is to say, by its rotation withthe button head or carrier it rotates the bobbin by lateral pressureupon one of the overlapping flanges of the bobbin catch or plate, andmoves the bobbin longitudinally in the one direction by the pull of thebutton-head on the overlapping flanges of the plate or catch as thebutton-carrier is slid in a given direction,said revolving and slidingbutton-carrier, as it is slid in the opposite direction, pressing on theoutside surface of the plate or head of the bobbin to reverse thetraverse of the latter. These bobbincatches are a great source ofannoyance and expense in a mill. They are constantly coming off thebobbin by the pulling or working of the button upon them, and have to'berenailed to their places with the nails in the same holes as before,thus making their retention very insecure. Furthermore, said catches andthe buttons, always presenting Serial No. 243,765. (No model.)

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents alongitudinal section of a yarn-winding bobbin hungto rotate and slide upon the dead or center spindle of the flier, andhaving my improved catch applied, also showing the rotating and slidingbuttoncarrier with attached button which drives the bobbin. Fig. 2 .is atransverse section upon the line or a: in Fig. l; and Fig. 3 is asectional View of the bobbin-catch having a smooth instead of ascrew-threaded exterior, as in Fig. 1.

A is the bobbin, fitted, as usual, to rotate and longitudinally slideupon the spindle B of the flier and within the flier, which latter isnot shown here,as it forms no part oftheinvention;

O is the button-carrier, and bits sleeve,with attached pulley c, fittedto rotate upon and slide along, as usual, the spindle B, outside of theone head 01 of the bobbin, for the purpose of rotating and reciprocatingthe bobbin longitudinally, the ordinary or any suitable means being usedto rotate and reciprocate the button-carrier through its pulley c.

D is the button or driver secured to the carrier O at any suitabledistance from its center.

E is the bobbin-catch applied to the head d of the bobbin, and arrangedto engage with the button D. This bobbin-catch isin the form of acircular thilnble, and may either be plain, as shown in Fig. 3, on itsexterior, and be driven to its place within a circular hole made throughthe head of the bobbin, and maybe cylindrical or tapering on itsexterior, or have a screw-thread on its exterior and be screwed into thehead of the bobbin, as shown in Fig. 1; or it may be otherwise fixedlysecured in the head of the bobbin. Said thimble-like bobbincatch isconstructed with an interior flange, s,

on its outer end, for the head of the button D to engage with to draw orslide the bobbin in the one direction, while the shank of the button,pressing upon the inner peripheral surface of the flange 8, serves torotate the bobbin.

This construction of the bobbin-catch will very greatly reduce cuttingand wear of the button and its catch, and the catch or thimble may beturned in its seat from time to time to change the wearing-surfaces, andso further prolong the durability of the catch, while its firm andsecure attachment Within the head of the bobbin does away with allliability of its working loose or falling out.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The within-described bobbin-catch for yarn-spinning machines, thesame consisting of acircular thimblc having an iuteriorflange on itsouter end, substantially as specified.

2. The combination,with the bobbin A, having a circular aperture in oneof its heads outside of the axial center of the bobbin, of the circularthimble-likebuttoncatoh E, fitted within said aperture and provided withan interior flange, 3, on its outer end, essentially as described.

3. The combination of the button-carrier G and its attached button D,the spindle B, the bobbin A, and the circular thimble-like bobbin-catchE, having an interior flange, s,upon its outer end, substantially as andfor the purposes herein set forth.

ISAAC L. ALLEN.
